“…It was suggested that water/water-laden comets and asteroids may have deposited the water. If water does exist in those craters, it was conjectured by Chua and Johnson (1998) that the moisture distribution may consist of water-ice mixing with the regolith to saturation or near saturation, and reducing outwards according to the matric suction pressure (which is influenced by the particle size distribution and is defined as the pore air pressure minus the pore water pressure). Since the gravitation potential is relatively small compared to the matric suction potential, the water would have been drawn laterally or even upwards over some distance.…”

This paper aims to summarize the evolution of lunar base concepts over the past approximately half-century. We will discuss the various classes of concepts, the lunar environment as it pertains to structural design, construction, and human habitation. Topics introduced are: The Lunar Surface Environment; Lunar Base Concepts During the Apollo Era; More Recent Concepts for Lunar Structures; Futuristic Concepts and Applications.

“…In recent years, Saal 6 and Hauri 7 demonstrated that there may be water on the Moon. However, the Lunar Prospector Mission team indicated that the moisture content in the regolith at the bottom of the crater might be between 0.3% and 1% 8 . Therefore, the utilization of such a low level of water is not realistic, and the cost is high.…”

The environment on the lunar surface poses some difficult challenges to building long-term lunar bases; therefore, scientists and engineers have proposed the creation of habitats using lunar building materials. These materials must meet the following conditions: be resistant to severe lunar temperature cycles, be stable in a vacuum environment, have minimal water requirements, and be sourced from local Moon materials. Therefore, the preparation of lunar building materials that use lunar resources is preferred. Here, we present a potential lunar cement material that was fabricated using tektite powder and a sodium hydroxide activator and is based on geopolymer technology. Geopolymer materials have the following properties: approximately zero water consumption, resistance to high- and low-temperature cycling, vacuum stability and good mechanical properties. Although the tektite powder is not equivalent to lunar soil, we speculate that the alkali activated activity of lunar soil will be higher than that of tektite because of its low Si/Al composition ratio. This assumption is based on the tektite geopolymerization research and associated references. In summary, this study provides a feasible approach for developing lunar cement materials using a possible water recycling system based on geopolymer technology.
